从China供应商批量进口8 Layers Pcb With Bga And Golden Fingers

This 8-layer PCB is designed for high-performance electronics, featuring a minimum line width and space of 4 mil, which allows for dense circuit layouts. The board has a thickness of 1.20 mm and uses immersion gold as the surface finish, providing excellent conductivity and corrosion resistance. The minimum drilled hole diameter is 0.8 mm, accommodating fine-pitch components like BGAs, while the golden fingers enable reliable edge connections.

The immersion gold finish is applied over a nickel barrier, typically 3 to 6 µm thick, which prevents copper diffusion and ensures long-term solderability. BGAs (Ball Grid Arrays) on this PCB are suited for high-speed signal routing, with standard ball pitches ranging from 0.4 mm to 1.0 mm. Golden fingers, plated with hard gold (typically 1 to 3 µm), are used for edge connectors and are rated for at least 1,000 insertion cycles in standard applications.

These PCBs are used in telecommunications, consumer electronics, and automotive systems where high-density interconnects and reliable edge connections are required. The 8-layer stack-up typically includes two to four signal layers, two to four plane layers, and prepreg materials with a standard dielectric constant of 4.2. Buyers often source these in panel sizes of 18 by 24 inches, with a standard copper thickness of 1 oz (35 µm) for outer layers and 0.5 oz (18 µm) for inner layers.

Cyzon Limited is based in the Huafeng Building on Yuan Road in Shenzhen, Guangdong, a region known for its concentration of electronics manufacturing suppliers. The company is classified as an imported-tier seller with a harbor-level trust signal, indicating verified trade activity but no recorded response metrics in the current data.

The supplier lists this 8-layer PCB with BGA and golden fingers as a high-precision product, with specifications tailored for complex electronic applications. No additional details about certifications, production scale, or client history are provided, so buyers should directly confirm compliance with their technical and quality standards.
